Because of porosity of the filter paper some of the CaC2O4*H2O precipitate passes through the filter paper. Will the reported percent of the limiting reactant in the original salt mixture be reported too high or too low
suppose 321 grams of methylamine ch3nh2 and 332l of oxygen gas are mixed together in the reaction below at stp. how
upon catalytic hydrogenation unknown Z gives cyclooctane. Oxonolysis of Z followed by reduction with dimethyl sulfide, gives a three0carbon dialdehyde and a five-carbon dialdehyde. Draw the stucture of Z.
Draw the Lewis dot structure for the CIBr5. What is the molecular geometry? a) trigonal bipyramidal b) square pyramidal c) square planar d) seesaw
what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding hydroiodic acid) Hypochlorous acid HClO Ka1=3.5x10-8
Based on coulombic attractions, list the magnitude of attraction between ions from the least to highest. why? Nacl, Na2SO4, MgSO4
Determine the amount of heat produced when 100g of CH4 combust, CH4 + 2O2 yields CO2 + 2H2O + 1063kJ
Use the Ideal Gas Law in the form n=PV/RT. Remember to change all units to correspon to the values for the gas constant. R=0.0821 L*atm/mol*K.
How much heat is absorbed in the complete reaction of 3.00 grams of SiO2 with excess carbon in the reaction below? DH0 for the reaction is +624.6 kJ.
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0M AgNO3 solution and a strip of Cadmium metal in a 1.0M Cd(NO)3 solutio. the circuit is completed by a wire and a salt bridge in the usual way.
